About Body Mass Index

It's important to realize that BMI is not the most accurate determination of whether or not you are at an unhealthy weight. For example, if you are extremely muscular, your BMI may show as "Overweight" or even "Obese," when you're not. Also, if you are a "Normal" BMI, but have a very high body fat percentage, you may have the same health risks as someone with an "Obese" BMI.

BMI is only one tool in your health arsenal. It is basically just a ratio of your height to your weight.

Body mass index (BMI), which was established in 1998 by The National Institute of Health, estimates a person's body fat and health risks. For most people, the BMI provides a more accurate estimate of a person's weight-related health risks over the standard height and weight tables or weight alone.

The BMI estimates your percentage of body fat using your height and weight. Based on this estimate, if your BMI numbers are at or above 25, you are considered unhealthy and could be at an increased risk of having higher blood pressure, diabetes and risk of heart disease and stroke.

Please keep in mind that the BMI is only a guide and is not exact. BMI does not consider individual factors such as bone or muscle mass to provide a more accurate assessment of your overall health. For instance, if you are physically fit, your BMI may be high, or if you have low muscle mass, BMI may underestimate your body fat. Also, if you have excess abdominal fat, BMI may inadequately evaluate your health risks.

Use the BMI as an estimate only of your body fat and health risks. We recommend you consult with your doctor to receive a more accurate evaluation.
